PULLEY AND ROPE OR CABLE HOLDER.

Specification of Letters Patent.

Application filed June 18, 1908.

Patented March 23, 1909.

Serial No. 439,250.

To all whom it may concern: 1

Be it known that I, GEORGE J. BATZER, citizen of the United States,residing at Cleveland, in the county of Cuyahoga and State of Ohio, haveinvented certain new and useful Improvements in Pulley and Hope or CableHolders, of which the following is a specification.

This invention is a combined pulley and rope or cable holder, comprisinga pulley or block provided with a hook, and having camlocking deviceswhich may be applied to the ro e to hold or clutch the same upon the puley.

The device will be found particularly useful in connection with clotheslines, to hold the line as desired, but it is not limited to such useandmay be applied anywhere, to hold a rope or cable of any size.

The invention is illustrated in the accompanying drawings, in which-Figure 1 is a side view, partly broken away; Fig. 2 is a section on theline 2-2 of Fig. 1; Fig. 3 is a detail in side view of a modification;and Fig. 4 is a section on the line 44: of Fig. 3.

Referring specifically to the drawings, the frame of the pulley orsheave consists of a, cheek plate 3 provided at one end with a hook 1,for which a ring or other attaching device may be substituted, accordingto the 1 place where the sheave is to be attached. A l lip, 2, projectsfrom the shank of the hook and forms a recess for the housing of the campivots and the spring. The ground wheel 8 is fixed to the cheek 3 by thepivot 9, and the described construction forms an open sheave so that therope can be caught over the wheel without pulling through.

To hold the rope wherever desired, and lock the pulley wheel, a pair ofcams 4 is provided, pivoted by pins 6, and located on opposite sides soas to catch in either or both directions. The holding faces of the camsare notched, and when either cam is turned in to engagement with therope on the ulley wheel, it binds and holds the same an locks thepulley. At its inner end each cam piece has a knuckle 10 pressed by oneend of a coiled spring 7 housed in the recess under the lip, and the cammay be turned to cause the s )ring to bear on opposite sides of theknuce and thus hold the cam in or out of engagement with the rope.

In the modified form shown in Figs. 3 and 4, instead of the wheel 8 asemi-circular grooved guide 1 1 is provided, projecting from the cheek3, and the rope slides on this guide. The same kind of locking device isused. Where it is desired to hold a rope in one direction only, one ofthe cams can, of course, be omitted. Also, the wheel may be duplicated,forming a double pulley, and one or more of the locking devices appliedto each. Various other modifications may be made, within the scope ofthe invention.

I claim:

1. A sheave provided with a rope catch consisting of a cam pivoted inthe sheave frame and arranged to swing toward or from the sheave wheel,and to bind a r0 e against the wheel, the cam having a knuc e, and aspring held in the frame and bearing against the knuckle and adapted tohold the cam in or out of contact with the rope.

' 2. A rope catch for a sheave, comprising a pair of opposite camspivoted in the sheave frame, and having knuckles, and a spring held inthe frame and bearing at its opposite ends on said knuckles and adaptedto hold the cams in or out of contact with the rope.

In testimony whereof I afiix my signature in presence of two witnesses.

GEORGE J. BATZER.
